# Part I
Getting Started

This part is intended to help you get started with the P G F package. First, the installation process is explained; however, the system will typically be already installed on your system, so this can often be skipped. Next, a short tutorial is given that explains the most often used commands and concepts of TikZ, without going into any of the glorious details. At the end of this section you will find some, hopefully useful, hints on how to create “good” graphics in general. The information in this section is not specific to P G F.

\tikz \draw[thick,rounded corners=8pt] (0,0) -- (0,2) -- (1,3.25) -- (2,2) -- (2,0) -- (0,2) -- (2,2) -- (0,0) -- (2,0);

# Part II
TikZ ist kein Zeichenprogramm

\begin{tikzpicture} \draw[fill=yellow] (0,0) -- (60:.75cm) arc (60:180:.75cm); \draw(120:0.4cm) node {$\alpha$}; \draw[fill=green!30] (0,0) -- (right:.75cm) arc (0:60:.75cm); \draw(30:0.5cm) node {$\beta$};
\begin{scope}[shift={(60:2cm)}]
\draw[fill=green!30] (0,0) -- (180:.75cm) arc (180:240:.75cm);
\draw (30:-0.5cm) node {$\gamma$};
\draw[fill=yellow] (0,0) -- (240:.75cm) arc (240:360:.75cm);
\draw (-60:0.4cm) node {$\delta$};
\end{scope}
\begin{scope}[thick]
\draw (60:-1cm) node[fill=white] {$E$} -- (60:3cm) node[fill=white] {$F$};
\draw[red] (-2,0) node[left] {$A$} -- (3,0) node[right]{$B$};
\draw[blue,shift={(60:2cm)}] (-3,0) node[left] {$C$} -- (2,0) node[right]{$D$};
\draw[shift={(60:1cm)},xshift=4cm]
node [right,text width=6cm,rounded corners,fill=red!20,inner sep=1ex]
{
When we assume that $\color{red}AB$ and $\color{blue}CD$ are
parallel, i.\,e., ${\color{red}AB} \mathbin{\|} \color{blue}CD$,
then $\alpha = \delta$ and $\beta = \gamma$.
};
\end{scope}
\end{tikzpicture}

# Part III
Libraries and Utilities

In this part the library and utility packages are documented. The library packages provide additional predefined graphic objects like new arrow heads, or new plot marks. These are not loaded by default since many users will not need them.

The utility packages are not directly involved in creating graphics, but you may find them useful nonetheless. All of them either directly depend on P G F or they are designed to work well together with P G F even though they can be used in a stand-alone way.

\begin{tikzpicture}[scale=2] \shade[top color=blue,bottom color=gray!50] (0,0) parabola (1.5,2.25) |- (0,0); \draw (1.05cm,2pt) node[above] {$\displaystyle\int_0^{3/2} \!\!x^2\mathrm{d}x$}; \draw[style=help lines] (0,0) grid (3.9,3.9) [step=0.25cm] (1,2) grid +(1,1);
\draw[->] (-0.2,0) -- (4,0) node[right] {$x$};
\draw[->] (0,-0.2) -- (0,4) node[above] {$f(x)$};
\foreach \x/\xtext in {1/1, 1.5/1\frac{1}{2}, 2/2, 3/3}
\draw[shift={(\x,0)}] (0pt,2pt) -- (0pt,-2pt) node[below] {$\xtext$};
\foreach \y/\ytext in {1/1, 2/2, 2.25/2\frac{1}{4}, 3/3}
\draw[shift={(0,\y)}] (2pt,0pt) -- (-2pt,0pt) node[left] {$\ytext$};
\draw (-.5,.25) parabola bend (0,0) (2,4) node[below right] {$x^2$};
\end{tikzpicture}

# Part IV
The Basic Layer

\begin{tikzpicture} \draw[gray,very thin] (-1.9,-1.9) grid (2.9,3.9) [step=0.25cm] (-1,-1) grid (1,1); \draw[blue] (1,-2.1) -- (1,4.1); % asymptote \draw[->] (-2,0) -- (3,0) node[right] {$x(t)$};

\foreach \pos in {-1,1,2,3}

\fill (0,0) circle (0.064cm);
\draw[thick,parametric,domain=0.4:1.5,samples=200]

plot[id=asymptotic-example] function{(t*t*t)*sin(1/(t*t*t)),(t*t*t)*cos(1/(t*t*t))}

node [below right,fill=white,yshift=-4pt] {$(\frac{2}{\pi},0)$};
\end{tikzpicture}

# Part V
The System Layer

This part describes the low-level interface of P G F, called the system layer. This interface provides a complete abstraction of the internals of the underlying drivers.

Unless you intend to port P G F to another driver or unless you intend to write your own optimized frontend, you need not read this part.

In the following it is assumed that you are familiar with the basic workings of the graphics package and that you know what TEX-drivers are and how they work.

\begin{tikzpicture}[shorten >=1pt,->] \tikzstyle{vertex}=[circle,fill=black!25,minimum size=17pt,inner sep=0pt] \foreach \name/\x in {s/1, 2/2, 3/3, 4/4, 15/11, 16/12, 17/13, 18/14, 19/15, t/16} \node[vertex] (G-\name) at (\x,0) {$\name$}; \foreach \name/\angle/\text in {P-1/234/5, P-2/162/6, P-3/90/7, P-4/18/8, P-5/-54/9}
